Scarlett knew she had to fit into a form-fitting catsuit for her latest movie role, so she amped up her exercise routine to include…Mexican wrestling!

Although Scarlett Johansson is one of the sexiest women in Hollywood, she knew she had to tone up to fit into her form-fitting Iron Man 2 catsuit. But how did the pouty-lipped vixen get in shape to play the Black Widow?

Added Iron Man 2 director Jon Favreau, “We combined a lot of different fighting styles. The biggest one was Lucha Libre, this Mexican wrestling style. I thought it would be a little comical, but when you see a woman doing [Lucha Libre] in a black widow costume —not a guy in a sequin cape — it has a much different effect.”

But what exactly IS Lucha Libre? Well, it’s pretty darn intense, and involves tons of high- flying aerial moves and tag-team wrestling matches. Although the moves reportedly took ScarJo a long time to master, her hard work definitely paid off: she looks bangin’ in her Black Widow bodysuit! And we bet her hubby Ryan Reynolds doesn’t mind her sporting the bodycon ensemble either!
